It isn't obvious to me, however. Suppose I add several JFXPanels into a 
single Swing top-level window. I may want to show a modal dialog for the 
first JFXPanel, but leave others operable, for example. This use case 
seems to be quite valid.

best regards,

If I show a JOptionPane and I give a JPanel as the "parent" component, does it block only the JPanel?  This is no different.  Can you give me an example of when you would only want the JFXPanel blocked?

>>> I responded earlier wondering why the native window handle of the Swing Window wasn't acquired via the publicly available jawt native methods so it could be used as the parent for a Stage or worked into some sort of hierarchy to give a proper parent window to FX Stages and dialogs.   I didn't see any response.  Am I missing something?
>>> I already do this (get and use the native window handle) in a Swing app so that I can blit live video into my Swing app., a high-end video capture/transcoder/broadcast application. (See http://www.digitalrapids.com/en/Products/StreamZHD.aspx or the one that really could have used FX if it was ready earlier http://www.digitalrapids.com/en/Products/TouchStream.aspx)
>>> I actually have a need to do the same with a JavaFX app .. but there is no equivalent in FX land for the jawt JNI methods. (I asked for this years ago in the Java FX 1.0 days.)
>>> Is all of the code involved in JFXPanel->Scene->Window Open Source?  I went poking around but didn't find the implementation of com.sun.javafx.tk.quantum.QuantumToolkit which I think is used to create the peer of the EmbeddedWindow used as the Window for JFXPanels.
